Embodiment Construction

[0029] With reference to the general diagram of FIG. 1 , reference numeral 1 designates a suction pump having at least one suction connection 2 and a delivery connection 3 to a collecting tank 4 . In most cases when suctioning different fluids which can be separated by decantation, the delivery connection acts as a decanting device. In the bottom area of ​​the collecting tank 4 a discharge pipe 5 is connected and in the top area of ​​the collecting tank 4 a ventilation pipe 6 is connected.

[0030] The suction connection 2 of the suction pump 1 is connected to the first space 7 from which the first contained fluid 8 is to be sucked; common features. Furthermore, according to the invention, the suction connection 2 of the suction pump 1 is additionally connected to the second space 10 from which the second contained fluid 11 is to be suctioned. The system also comprises means 12 arranged to cause intermittent operation of pumping said second fluid 11 by pump 1 in response to ...

Abstract

A suction system comprising a suction pump (1) having at least one suction connection (2,2',2'') and a delivery connection (3), a receiving reservoir (4) connected to the delivery connection (3), connecting pipings from a suction connection (2,2') to a first space (7) from which a first fluid (8) should be sucked, and connecting pipings from the delivery connection (3) to the receiving reservoir (4), characterized in that the system further comprises a connecting piping (14,15,16) extending from a second space (10), from which a second fluid (11) should be sucked, to at least one suction connection (2,2',2'') of the pump (1), and comprises a device (12) disposed for causing an intermittent operation of the second fluid suction by the pump (1), responsive to the level reached by the second fluid (11) in the second space (10). Preferably, the pump (1) is a vacuum pump, the first fluid (8) is air, the first space (7) is a depressurized reservoir, the second fluid (11) is oil and the second space (10) is a space wherein oil (11) has a tendency to accumulate. The system is especially, but not exclusively, intended for automotive applications.

Description

technical field [0001] The invention relates to a system for pumping a fluid which has the additional function of pumping another fluid. Background technique [0002] Such a system is well suited for application to an air suction system that can additionally suck oil, and is particularly suitable for use in automotive applications; the invention will therefore be elucidated in detail by way of example with reference to the above application, but it should be understood that the invention can have Possible applications in other fields to pump various fluids. [0003] The air suction pump is used in the automotive field, the so-called "vacuum pump". The function of the vacuum pump is to generate a low pressure in a specific container, which is commonly referred to as "vacuum". Utilizing a power booster), a servo brake device operates pneumatically to amplify the force applied by the driver to the brake pedal to activate the vehicle's braking system. [0004] The same vacuum ...
